To all whom it'may cm'wem: I

Be it known that I, JOHN LENCE, a subject of the King of Great Britain, residing at Regina, in the Province of'saskatchewan and Dominion of'Canada, have invented certain new and useful Improvements'in Vvashing, Scrubbing, and Drying-Machines, of

which the following is aspecifi'cation.

This invention relates "to' machines for washing, scrubbing and drying floors, and.

the primary object of the invention is to" provide an improved machine whichwill effectively wash, scruband dry affloor without the necessity of, a person washing the fleorgetting on theirhands andlrnees,

Another object of the inventionis to provide an improved floor washing, scrubbing and drying machine which will permit of floors being quickly and thoroughly cleaned and which entirely eliminates the usual labor associated therewith. A further object of the invention is the provision of an improved floor cleaning machine embodying an endless washing cloth, an endless drying cloth, and a rotary scrubbing brush arranged between the cloths, the

Washing and drying clothshavingmeans for permitting the dirty water" to be removed therefrom, the washing cloth also having means for regulating the amount of clean water carrier thereby.

''A still further object of the invention is the provision of an improved floor washing machine of the above character which is durable and efiicient in use, one that is simple and easy to manufacture, andone which can be placed upon the market at reasonable cost.

With these and other objectsin view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more fully described, claimed and illustrated in the accompanying drawings, forming a part of" this"specification, in which drawings: f r r I Figure 11s a slde elevation of'the improvedfioor cleaning machine. 7 I I Figure 2 is a longitudinal section through the same.

Figure 3 is an: end elevation of the machine showing, parts thereof insection.

Figure 4 is a transverse section through the improved machine. I Y '1 Figure 5 is an enlarged fragmentary deitail "side elevation of the improved machine showing the means for adjusting one of." the wringer rollers so as to effectively squeeze drying cloths. T I it gure 6 is an enlarged fragmentary ,deitail horizontal sectionthrough the machine rtion of the rollers, for regulating the amount rod? water carried by the washing cloth, in relatien to each other. i .Referring to the wherein similar reference characters desig- 5 corresponding'parts throughout the sevaer'af'i views, the letter A indicates the improved washing, scrubbing and drying niaehine and the same includes a frame B which supports the floor washing device 6, the recrubbii'ig device D and the drying device E. The frame B includes'a pair of parallel :spaced longltudinally extending side bars 10 :and the end bars 11, which have their inner faces inclined asat 12 for a purpose which ."Wlll hereinafter more' fully appear. The Ilongitudinally extendingbars 10 adjacent to their outer endssupport the upstanding ver "tically disposed bars 18 which support the drawings, in detail,

illustrating the means for adjusting the posi- ":side walls 14:. Theside walls l imaybe of any preferred material, either of wood, or sheet metal. 'The'side, walls 14 terminate :shortof the frontportion of the long1tudianally extending bars 10 as clearlyshown-in' the drawings and the front vertical bars'are ibraced against movement by diagonally extending inclined front'brace bars 15.

The improvedwashingf device C is-arranged at the forward end of the machine and includes an endless cloth 16and a substantially v shaped water receivingtank 17 into which the endless belt 16 is adapted to extend so thatthe belt may be thoroughly saturated with the cleaning fluid before cominginto'contactwith the floor or other surface to be cleaned; It is to be understood that the tank 17 can receive any suitable or Y-desired eleanin'gfluid such as hotsoapy water; vThe lower end of the endless belt 16 is trained around a transversely extendsitely extending coil "springs 21 are secured to the upper ends of the arms 19 and these coil springs" normally tend to hold the roller 18 in correct position in relationto to the frame of the machine, A guide roller 22 is rotatably supported by the walls of the tank 17 and is located adjacent to the lower end thereof so that the belt will pass through the cleaning fluid. The guide rollers and 2d are also carried by the side walls of the tank and these rollers are arranged adjacent to the front and rear ends of the tank so as to effectively guide the belt in and out of the tank. A wringer 25 is arranged directly below the guide roller 23 and the endless belt passes between the rollers thereof and this wringer forms means for eiiectively squeezing the dirt and water from the belt. .tl means 26 is arranged be low and in front of the guide roller 24 for regulating the amount of the cleaning iiuid cairied'by the beltand this means consists of a pair of rollers 27 and 28, which engage the upper and lower surfaces of the belt. The roller 28 has its terminals rotatably carried by the side walls 14:. The upper roller 27 has its terminals mounted in sliding blocks 29 whichare carried by frames 30 secured to the side walls 14. The blocks are normally held in a raised position by springs 31'and adjusting screws 32 are provided for engaging the blocks 29 for normally urging the same downward in the frame. Thus it can be seen that by adjusting the screws 32 the pressure which the roller 27 bears against the roller 28 can be readily adjusted thereby permitting the quantity of cleaning fluid squeezed from the cloth to be regulated.

The longitudinally extending side bars 1O carry the depending bearings 33 which are located on the opposite sides of the trans- SC-Psi? center of the machine and these bearings rotatably carry the supporting shafts 3 5?v tor the traction wheels 35. Certain of the traction wheel's have relatively large sprocket wheels 36 secured thereto, around which is trained a drive sprocket chain 37 for a PUIPOSGWVhlCl'l will hereinafter more fully appear. 1

Located intermediate the pairs of traction wheels 35 is the scrubbing diet ice D which includes a rotaiybrush 88. The brush 38 consistsofa roller 39 which carries a plurality of spaced rows of spirally arranged bristles 40 and the roller carries a shaft'tl the terminals oii which are rotatably mounted in a suitable substantially inverted 'U- shaped bracket 1-2 which is secured to a centrally disposed transversely extending beain 'be rotated therewith.

The shaft 41 has secured thereto a sprocket wheel and this sprocket wheel engages the lower run of the drive sprocket chain 37. Thus it can be seen that when the machine is pushed over a surface to be cleaned that the scrubbing brush 38 will Une end of the shaft is extended beyond its bearing and carries a pair of spaced sprocket wheels 45 and directly inrear of the. scrubbing brush 38 and the same includes an endlessbelt- 47 the lower end of which is held into tighten- 3 carried by-arins l9 which are slidably carried by the sidebeanis 1Ov The arnis 4c9 are normally held in lowered position so as to hold the roller eeinto tight engagement with the belt at? by ineansof contractile coil 11 sprin 50 which have one of their terminals sccu l to the arms 49 and their opposite terminals to 3, ns carried by the side beams bot which. is 1fl"31gG(l. adjacent to the rearend ot the mach he and this roller 51 provides means for guiding the belt l'fadjaceht to the lower end of the tank. Guide rollers 53 and i roller 1 is arranged adjacent to the am. of a' substantially V-shaped tank 52 5e are arranged adjacent to the front and rear portions or" the tank of the upper ends threof so as to guide the belt into and out of the tank. A wringer 55 is carried by the side walls Hand is arranged directly in can be seen that as the belt -17 comes out of the tank 52 all water will be effectively squeezed cm the belt 45?.

The wringers 2F and 55 for the endless be his 1 1' same and each includes upper and lower lers 56 and. The lower roller 57-is rol l C arried by the side walls 14 while h the upper roller 56 is rotatably carried by t s i i liding blocks 58 which are mounted'in ro 59 secured to the side walls 14:. The sliding blocks are normally held in a raised position by means of coil springs 60 and the tl'iiinibsciews 61 are provided for and t? are constructed identically rout of the guide roller 54: and thus it normally moving the roller 56 away from 7 around.respectively the sprocket Wheels 62 and 46 2uid 63iand 45. 'Thus when the traction wheels 35 are rotated the brush 38 and the belts 16 and 47 will be operated.

Each of the tanks 17 and 52 are provided with drain valves 66 and 67 and these valves permit all water to be drained from the tanks when desired.

. regulated by the rollers 27 and 28. The

endless belt 16 comes into contact with the surface to be cleaned and effectively washes the same and as the belt returns to the tank 17 the wringer 25 squeezes all of the dirty water therefrom. After the surface to be cleaned has been acted upon by the belt 16 the rotary brush 38 will come into contact with and thoroughly brush the surface, aft-er which the drying belt 47 engages the surface and effectively dries or mops the same. As the endless belt 47 travels through the tank 52 the wringer 55 squeezes all of the dirty water therefrom and when the portion from which the water has been squeezed again comes into contact with the surface being cleaned the same will absorb more of the water.

Changes in details may, be made without departing from the spirit or scope of the invention; but,
